Follow the RetroPortingToolKit transfer in submodule URLs and tooling

recomp-net, retcomm-rbengine (now rbengine), retcomm-toolchains (now
RetroPorting-Toolchains), the catalog and the launcher moved from
TechnicallyComputers to the RetroPortingToolKit org. GitHub still
redirects the old repo URLs, so nothing is broken today — but this repo
is what every port inherits its .gitmodules from, so the old owner
propagates into each new clone until it is fixed here.

.gitmodules now names the new URLs. The toolchain repo is updated in the
CI action default, the codegen host, fetch_toolchain.sh, toolchain_pack
and package_setup_host, and the scaffolder's recomp-net / rbengine
defaults follow.

Two things the mechanical sweep would have missed:

- render_launcher_block() held a second copy of the launcher slug split
  across two string literals, so a search for the full slug did not see
  it and every regenerated README kept the dead owner. It is now derived
  from LAUNCHER_REPO, which is the only place the slug lives.

- readme_has_launcher() matched one exact slug. Pointed at the new one
  alone it would report every port built before the transfer as missing
  its launcher section, and append a second copy to any README carrying
  neither the markers nor a "## RetComM Launcher" heading. It now
  accepts both.

The scaffolder's default GitHub owner for new ports becomes
RetroPortingToolKit. Existing ports are unaffected — they carry their
own owner in the README and remote.

psxrecomp, snesrecomp and recomp-ui did not move and still point at
mstan. Submodule paths (lib/recomp-net, lib/retcomm-rbengine) are
unchanged: they are pinned by every port and are not repo slugs.
